The network of the Rhaetian Railroad (RhB) offers all sorts of spectacular moments with a route length of 384 km / 240 miles. While the Albula and Bernina Lines, which have both been counted since 2008 as Unesco World Heritages, are known widely, the Arosa Line is still something of a secret tip. It was built in 1914 by the Chur-Arosa-Railroad Stock Company and was not merged with the RhB until 1942. Up until then, the trains running to Arosa were underway in the light blue / light gray paint scheme. After the merger, they were painted in the former RhB paint scheme of green/beige, until they were changed later to a gleaming red. They still currently wear this paint scheme.The Bernina Railroad was also unique until 1943. The entire route St. Moritz – Tirano was finished in 1910. The locomotives and cars were then given a snazzy yellow design. The Allegra dual voltage powered rail car trains have been underway on the RhB network since 2009, and this has been mostly on the Arosa and the Bernina lines. When an overhaul came due on Allegra ABe 8/14 3514, the decision was made to paint this train in remembrance of the once independent railroads in their historic paint schemes. The center car was given the historic RhB color scheme. Since December of 2023 this powered rail car train has not been shown in the familiar RhB red. It has been wonderfully colorful. This was the origin of the Ancestor Train, as the RhB affectionately calls the 3514. It is not just an attention getter, but rather homage to the once independent railroads in the Canton of Grisons.

The Allegra 3514 has a special paint scheme: One end car is in the yellow of the former Bernina Railroad, the other end car is in version of the Arosa Railroad – light blue / light gray, the middle car represents the Era III green/cream of the RhB. This powered rail car train called the Ancestor Train is underway on the RhB network in this design.
This is a model of an RhB class ABe 8/12 Allegra, road number 3514, powered rail car train. The paint and lettering are prototypical for Era VI as the so-called Ancestor Train, which represented the earlier paint scheme of the Bernina Railroad, the Rhaetian Railroad, and the Arosa Railroad. The model has traction tires and is driven on four wheelsets by two powerful motors. It has an mfx/DCC sound decoder with many sound and light functions. The pantographs can be raised and lowered digitally on both end cars. All the cars on the train have metal wheels, and the center car has wheelsets with ball bearings. All the doors can be opened. The model has many separately applied details such as conductors, plugs, windshield wipers, antennas, and rear-view mirrors. The model has sprung buffers and complete rail clearance devices (the center part of the rail clearance devices can be replaced with a standard LGB coupler that is included with the train). Length over the buffers 206 cm / 81-1/8.

An attention getter on the route network of the Rhaetian Railroad since the middle of December 2023.

The running sounds will also work in analog operation.
